Preparation and Study of CdO-CdO2 Nanoparticles for Solar Cells Applications

Abstract:

—In this study, (CdO) thin film, which was prepared by chemical method and deposited by drop casting technique on glass and silicon substrates have been studied . The structural, optical and chemical analysis were investigated. X-ray diffraction (XRD) measurements reveal that the (CdO) thin film was polycrystalline, cubic structure and there is no trace of the other material. UV-Vis measurements assure that the energy gap of (CdO) thin film was found to be 2.5eV. I-V characterization of the solar cell under illumination at 40mW/cm2 fluence was investigated . The open circuit voltage (Voc) was 4.1V and short-circuit current density (Isc) was 1.44 mA. These measurements show that the fill factor (FF) and the conversion efficiency (η) ,were 36.2% and 6.8% respectively.
